Toshio Iwai about Time Stratum II: "In this installation, I placed 120 paper human figures on a motorised spinning disk. Iset up a video monitor above them, while strobing the light down, the paper figures all burst into motion.
By using a video monitor as strobe light, I could change the colour and speed of strobe lights with the music. The images are transformed with changes in the light."
